A coupled numerical approach is investigated for predicting combustion instability limit cycle
characteristics when the combustor contains a long flame. The test case is the ORACLES …

Abstract The Flame Describing Function (FDF) is widely used to model non-linear thermo-
acoustic phenomena, eg limit cycle oscillations in a combustor. The FDF is a weakly non …

This conceptual numerical study explores a possible strategy for control of unstable intrinsic
thermoacoustic (ITA) modes. Control of the ITA feedback loop has not been discussed yet …

This work addresses model order reduction for complex moving fronts, which are
transported by advection or through a reaction–diffusion process. Such systems are …

We experimentally investigate the forced synchronization of a self-excited chaotic
thermoacoustic oscillator with two natural frequencies, plane. This study extends the …

This paper examines and compares the commonly used machine learning algorithms in
their performance in interpolation and extrapolation of flame describing function (FDFs) …

This work demonstrates that a hybrid approach for linear thermoacoustic stability analysis
that combines the Linearized Navier–Stokes Equations (LNSE) with a global Flame Transfer …

In this paper, the dynamics and thermoacoustic stability of a laminar premixed flame are
analyzed using a linearized reactive flow (LRF) solver. The LRF solver is based on …

This paper demonstrates the ability of neural networks to reliably learn the nonlinear flame
response of a laminar premixed flame, while carrying out only one unsteady CFD simulation …

In this paper, non-intrusive polynomial chaos expansion (NIPCE) is used for forward
uncertainty quantification and sensitivity analysis of thermoacoustic stability of two premixed …
